Abstract
A sensitive and stable signal multiplied quinone-linked immunosorbent assay (Multi-QuLISA) was developed. In Multi-QuLISA, an oligomerized quinone linked to biotin, namely biotin-8mer-naphthoquinone (Bio8mer-NQ), is used as a signal-generating label. Bio8mer-NQ is formed from a dendrigraft poly-l-lysine generation 1 (DPLL G1), a controlled branched oligomer composed of eight lysine moieties with nine free amino groups as a backbone. One of the nine amino groups of DPLL G1 is attached to biotin moiety, while the other eight are attached to 1,2-naphthoquinone-4-sulfonate (NQS). Bio8mer-NQ labels a biotinylated detection antibody using avidin as a co-binder. Then, multi-quinones in Bio8mer-NQ undergo a redox cycle with dithiothreitol and luminol, generating strong chemiluminescence. Standard ELISA uses a label enzyme that suffers from vulnerability in different conditions and poor stability. Bio8mer-NQ showed better stability than the enzyme (biotin-HRP) under different drastic pH and temperature conditions, hydrolytic enzymes, etc. Furthermore, Bio8mer-NQ was used as both chemiluminescence and colorimetric label based on the redox cycle of quinone, and it had LODs of 1.5 and 6.5 nM, respectively. The method could detect biotinylated immunocomplex in an in-house designed immunoassay down to 0.2 nM, which is about 25 times more sensitive than biotin HRP. Eventually, Bio8mer-NQ was applied successfully in Multi-QuLISA for detecting β-casein with a sensitivity of 3.2 ng/mL, while the conventional ELISA had an LOD of 35 ng/mL. Overall, Bio8mer-NQ is a stable compound that could be used as an excellent replacement for the enzyme in immunoassay and can be used in both colorimetric and chemiluminescence assays with good sensitivity.

Automatic label-free immunoassay with high sensitivity for rapid detection of SARS-CoV-2 nucleocapsid protein based on chemiluminescent magnetic beads. SENSORS AND ACTUATORS. B, CHEMICAL 2021; 349:130739. [PMID: 34611381 PMCID: PMC8481120 DOI: 10.1016/j.snb.2021.130739] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/18/2021] [Revised: 09/07/2021] [Accepted: 09/08/2021] [Indexed: 05/26/2023]
Abstract
Accurate and efficient early diagnosis is crucial for the control of COVID-19 pandemic. However, methods that can balance sensitivity, high throughput, detection speed and automation simultaneously are still scarce. Here, we report an automatic label-free chemiluminescence immunoassay (CLIA) for rapid SARS-CoV-2 nucleocapsid protein (NP) detection with high sensitivity and throughput. N-(4-aminobutyl)-N-ethylisoluminol and Co2+ dual-functionalized chemiluminescent magnetic beads (dfCL-MB) were first applied to the detection of protein by a novel and simple strategy. Sulphydryl polyethylene glycol was coated on the surface of dfCL-MB so as to assemble dfCL-MB and antibody conjugated gold nanoparticles through Au-S bond. Considering the high-risk application scenarios, the immunosensor was integrated with an automatic chemiluminescence analyzer so that the whole testing procedure could be carried out automatically without manual operation. A linear correlation between CL intensities and the logarithm of NP concentration was obtained in the range of 0.1-10,000 pg/mL with a detection limit of 21 fg/mL. The whole process cost 25 min and the sample compartment can bear 24 samples simultaneously. The spiked human serum samples and serum samples from COVID-19 patients were determined with satisfactory recoveries of 91.1-109.4%, suggesting that the proposed label-free CLIA is of great potential for SARS-CoV-2 NP detection in practice.

Abstract
Titanium dioxide (TiO2) nanostructures exhibit a broad range of theranostic properties that make them attractive for biomedical applications. TiO2 nanostructures promise to improve current theranostic strategies by leveraging the enhanced quantum confinement, thermal conversion, specific surface area, and surface activity. This review highlights certain important aspects of fabrication strategies, which are employed to generate multifunctional TiO2 nanostructures, while outlining post-fabrication techniques with an emphasis on their suitability for nanomedicine. The biodistribution, toxicity, biocompatibility, cellular adhesion, and endocytosis of these nanostructures, when exposed to biological microenvironments, are examined in regard to their geometry, size, and surface chemistry. The final section focuses on recent biomedical applications of TiO2 nanostructures, specifically evaluating therapeutic delivery, photodynamic and sonodynamic therapy, bioimaging, biosensing, tissue regeneration, as well as chronic wound healing.
